From 7cf4206a99d1b3e61bdbc7cbbf4a7bf6a9dfcc68 Mon Sep 17 00:00:00 2001 From: Dmitry Kasatkin Date: Wed, 9 May 2012 17:37:56 +0300 Subject: Remove unused code from MPI library MPI library is used by RSA verification implementation. Few files contains functions which are never called. James Morris has asked to remove all of them.
